net,net/netip: implement the encoding.(Binary|Text)Appender
Implement the encoding.TextAppender interface for "net.IP".
Implement the encoding.(Binary|Text)Appender interfaces for
"netip.Addr", "netip.AddrPort" and "netip.Prefix".
"net.IP.MarshalText" also gets some performance improvements:
│ old │ new │
│ sec/op │ sec/op vs base │

All exported types in the standard library that implement the
"encoding.(Binary|Text)Marshaler" now also implement the
"encoding.(Binary|Text)Appender".
